METHOD OF PACKETING TEA. OR THE LIKE.

Application filed November 1, 1921. Serial No. 512,161.

To all whom it may concern:

Be it known that I, SIMON Coornn, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements'in Methods of Packeting Teaor the like, of which the following is a specification.

This invention relates to the packetlng of materials, to a new andimproved form of packet, and particularly to a method for facilitatingand increasing the speed of production of packets of a general type suchas is used in packeting tea in individual containers.

In a companion application Serial No. 454,707 filed March 23, 1921.,there is d1sclosed and claimed a packet for tea or other material formedof a'blank folded on itself and stitched along the meeting edges. Theblanks for such packets are individually formed and individuallyoperated on in the making of the packets. In the present invention anelongated blank is used which is folded longitudinally on itself and, bya series of stitching and charging or filling operations, a series orsuccession of filled packets is rapidly produced in the blank or stripof material, the individual packets being separated from each other onlyafter they have been completely formed and filled as indicated.

By this method of producing the filled,

" increased over the production of packets or containers of a similargeneral nature heretofore known in the art. In addition the packetforming operations are more easily and economically accomplished and apractical and inexpensive packet is obtained.

Other features of the invention will be hereinafter referred to.

In the drawings in which two preferred forms of the invention areillustrated.

Figure 1 is a view in plan of a suitable blank and showing the progressof a series of operations thereon to convert the blank into aplurality'of packets for tea or other material.

Figure 2 is a view in side elevation of a completed filled packet.

Figure 3 is a view in cross-section taken on the line 3-3 of Figure 1and showing the operation of fillin or charging one of the packetsections of t e blank median line 6 to bring the two plies of the stripthus formed into superposed relation with their free edges in orsubstantially in allnement or engagement with each other as at '7 in thedrawings. The longitudinally folded blank or strip thus provided isformed into a series or succession of packet form ng sections by thesimple operation of running transverse lines of stitches across thefolded strip of material between the lateral edges thereof as at 8 inFigure 1 of the drawing. The section of the strip which 1s thus'formedhas, as will be clear,

a closed edge formed by the fold in the folded strip and two closedsides formed by the two lines 8 of stitching as indicated.

The fourth side of the packet is similarly closed by a line of stitchingsuch as is indicated at 9 in Figure 1 of the drawing.

The stitching operation may be performed by first forming the twotransverse lines 8 of stitching when thetea or other material is chargedor filled into the packet through the remaining open edge formed by thefree edges of the plies of the strip. The filling operation having beenperformed, the open side of the packet may be.closed by then running thethird line of stitching 9 along the edge and along the two transverselines of stitching 8.

A preferred way, however, of performing the operation of forming thepackets is indicated in Figure 1 of the drawing. In this method ofoperation the operation of stitching is begun at an upper right-handcorner of a packet section as at 10 in Figure 1 of the drawing andproceeded with to form the first transverse lines of stitching 8. Theline 8 having been completed, the stitched line 9 is then produced, theline being extended to a point beyond the mass of tea or other material11 which has been charged or filled into place previous to the Ibeginning of the stitching operation.

' hich. may be accomplished .by..any suitable;

The operation just described is repeated again and again to enclose eachindividual massof tea ll in the series of charges that are fed intoposition'between the plies ofthe blank at the proper intervals throughthe operationof a sultable filling machine spout is indicated at 12 Inthe. form of. the invention meats in Figure 1 the individual packetsformed etile inateri I charges'offilling material between the plies ofthe blank atone section thereof and runare square or substantiallysquare in conformation. It will be clear that the particu- 1 larshapeaswell as the particular size of the packets-1c n be varied betweenwide limits within he invention. a Another 'desirable form for packetssuitable for holding tea is that shown'in Figure '5 of the drawing inwhich it will be seen that the transverse lines of stitching' 8 whichare produced in the blank 5 haveaninclined or oblique position ascontrasted with lines of stitching Sin Figure 1 which are substantiallperpendicular to the lateral edges of the b ank.

tached by stitching or otherwise to a suitable identification. tag 14,the tag being sep- I i arate from the packetbya length of the 'Stitc gthread or cord 15 which provides Pa suitable sup orting member by meansof which the pee et may be handled.

4. That method of producing a filled tea rectangular blank of open-meshfabric with a charge of tea contained between the plies of'the fold,running a line of stitching from edge, and then extending the stitchingthread and attaching it to a tag element.
